A new version of the lan adapter patch is on
ftp://ftp.groessler.org/pub/chris/dreamcast/netbsd/lan-adapter
It also contains the patch to mb86960.c which I already submitted as
kern/17193.

Also there is the main file of the patch, lan_adapter.c, in plain
format (non-patch).

The driver now attachs to the g2 bus.

Can you give some examples?

In the mean time I did it the following way: The lana_match and
lana_detect functions memcpy the bus_space_tag they got from the g2
bus driver to local storage, and replace some entries with local
routines. The local routines adapt the offset and chain to the
original g2 routines.
